Which Toyota 4Runner year is most reliable?
2014–2019 (5th gen mid-cycle). The 1GR-FE 4.0L V6, 5-speed automatic, and part-time 4WD. Post-refresh interior and infotainment. As reliable as vehicles get.

The 5th-gen 4Runner (2010–2024) is one of the last body-on-frame SUVs with a naturally aspirated V6 and a real transfer case. Its reliability is legendary — but there are still smart years and less-smart years to target.
Bottom line: A 5th-gen 4Runner is one of the best long-term SUV purchases available — expect it to outlast its own body panels.

What makes these generations stand out.
The 1GR-FE 4.0L V6, 5-speed automatic, and part-time 4WD. Post-refresh interior and infotainment. As reliable as vehicles get.
Same drivetrain, updated safety tech and infotainment. Prices are high but the platform is proven.
The 4.0L 1GR-FE has been in production since 2003 with almost no failure-mode complaints — timing chains, port injection, robust bottom end.
The 5-speed automatic (A750F) is a proven Aisin design used across the Toyota truck line.
Part-time 4WD with a real 2-speed transfer case is simple and cheap to maintain compared to modern crossover AWD.
